I am working on a php script to control sabnzbd, xbmc and eventualy even transmission.
If there are people that would like to get involved, let me know!
At this point, i am busy on the sabnzbd part.
Next is going to be the xbmc, after that the transmission api (because that will be harder i guess)
Currently the plans are to finish the sabnzbd part, and then begin on the lay-out.
I was thinking to add the different modules as somekind of plugins, so for example that not every user has a transmission tab while they arent using it.
It would make it possible to add other api's in the future as well.
